About this course
There's no shortage of books out there on behavioural science and psychology. So it's fair to ask, do we really need another course?
Yes, we do. And this one is genuinely different.
A lot of the content you'll find online spends its time summarising research results. That can be helpful, sure, but it doesn't always help a marketer, or someone running their own business, make better decisions on Monday morning.
Instead of just pointing to studies, this course shows you how to use those ideas in practice, so your brand can perform even better.
Behavioural science can support every part of marketing. From pricing to promotions, from the channels you choose to the words you use. If your audience is made of humans, there's going to be something in here for you.
So how do we do it?
We'll cover a range of biases, not only the ones that everyone talks about. Then we'll walk you through how to apply each one.
And because having lots of options can feel messy, we also give you a straightforward way to navigate it all using a simple structure called C.R.E.A.T.E.S.
